 That's it - I had accidentally set two polygons to the same rank in eagle, connecting the +3V3 net to one of the motor outputs. Whoops! Fixed this by cutting the trace.
 
-So, to rev:
- - power lines are in sad, move to edge 
- - could do with only 2 mount holes, or three 
- - gnd plane is pretty dissatisfying
- - lights are a bit close, tend to solder together
- - just nix the usb, regulator, and power source switch
- - go to AEAT6600 encoder, but make sure you test it with the mkbldc first
- - min trace is still not 8mil for 2oz, should be
- - it would be cool to be able to heatsink from the top, maybe mount the driver on the bottom?
- - pull downs or, ? to avoid reset stepping
